Microphone reflection filter. With the same patented technologies as its larger siblings, the IRF2 was designed for drums, guitar cabinets, pianos, and confined spaces in general. The IRF2 uses a small curved wall of punched aluminum with 3 layers of polyester fiberboard separated with air gaps. These layers combine to help reduce room or stage ambience and isolate the mic from unwanted external noise. Dimensions: 197 x 190 x 101 mm. Weight: 0,68kg
